PRINTING OB TYPING. ADDING OR SUBTB-ACTING MACHINE OR TYPINGCALFULATDJ'G MACHINE Application filed February 5, 1929, Serial No.387,685, and in Austria February 7, 1928.

This invention relates to improvements in typing calculating machineswith printing mechanism, a transversely moving paper carriage and anumber of counters which are movable in accordance with or independentlyfrom the paper carriage.

The essential feature of the' present invention consists in this thatthe movable counters as well as the actuating mechanism therefore form aunit which is quite separate from the machine but can be fitted to anyexisting calculating machine. All that is necessary is to couple orconnect the actuating mechanism of the unit with the actuating mechanismof the I said calculating machine with printing mechanism.

The counters which may be of various sizes (capacity) are arrangedpreferably readily removable at desired distances apart on thepaper-carriage.

One mode of carrying out the present invention is illustrated by waj ofexample on the accompanying sheets of drawings in which Fig. 1 is a sideview of the arrangement.

Fig. 2 illustrates a similar view of differ ent parts of the machine.

Fig. '3 is a rear view of the paper carriage with the counters, and so aFig. 4 is a perspective view of a portion of thelmechanism shown in Fig.2 to an enlarged sca e.

Fig. 5 is a perspective view of a detail and Figs. 6, 7, 8 and 9illustrate the control mechanism in four diflferent positions.

Fig. 10 is a perspective general view of the machine according to thepresent invention. The parts in Fig. lillustrated by the thinlines showthe known construction of the typing calculating machine, whichessentially is provided with type-holders or bars 1 (covering each otherin the drawings), the stroke or movement of the same being limited inknown manner by adjustable members 2, which are operated by keys (notillustrated). When lifting the type-holders or bars by means of thedouble armed lever 3, operated by a hand-crank, and the pivotedconnecting rod'4, the raised position of the former depends on theoperative position taken up by the adjustable members 2 according to thenumber set at the time. The types of the individual type-holders or barsare disposed in a line, so that the set number can be printed on thepaper, passing over the platen-roller 5.

Before the return movement of the typeholders or bars the toothedsegments 6, which are connected with the levers 3, are placed in meshwith the wheels of the counter 8 by rocking the arms 7 in known manner,so that each counter-wheel takes up the return movement of thecorresponding type-holder.

The further arrangement according to the present invention isillustrated in thick lines in Fig. 1.

A U-shaped bar 12 is pivotally secured by means of arms 11 to the sidefaces of a slide 10, which carries the paper-roller 5. Thecolumn-counters 13 are arranged longitudinally movable on the said bar(Figs. 1 and 3). Clamping members 16 are secured to the lateral parts 15of the casings of the counters 13 by means of screws 16 and togetherwith the lateral parts 15 embrace the flange 12 of the bar 12. Thecasings with the counters can be shifted when the screws 16 areloosened, while the same are fixed by tightening thelatter. The objectthereof is to permit the suitable adjustment or setting of theindividual counters for the columnarrangement. The individual counters13 are successively operated by the type-holders or bars 1 by the feedof the slide 10, the number of counters 13 mounted on the bar 12corresponding to the number of columns to which the machine is adapted".For this object each type-bar 1 is provided with a dpin 1 each of whichengages the forked en of a lever 17, the other forked end of the latterengaging a pin 18 of aspringy rocking member 19, which engages alongitudinally movable rack 20. The movement of the rocking member 19brings it into engagement with a stop 20 mounted on the rack, so thatthe latter is. shifted after the rocking member engages the stop. Theprincipal object of the idle motion of the member 19 is to move thetype-bar 1 into the printing position of the figure nought by depressingthe noughtkc without influencing the rack 20 and thus an sequent-1y thecorresponding wheel of the counter 13. The idle movement of the lever 19also serves for rendering possible the tenstransmission.

Further during this idle movement various other adjusting movements arecarried out in the machine as will be described at a later stage. Thelever 19' comes against the stop 20 just at the moment when thenoughttype is disposed in the printing position. From this .moment therack 20 is moved downward, while the lever 19 is continuously pressedonto the stop 20 by the spring 19 The printing operation and at the sametime the return movement of all tens-transmission arresting p awls, 22bythe returnrail 25, as will be described later on, is carried outwhenever the type-bars 1 have taken up their highest positioncorresponding to the set amounts.

. The return movement of the lever 3 and thus of thetoothed segments 6and of the type-bars 1 commences after the engagement of the countersSand 13. The toothed segment 6 rotates the figure-disks of the counter 8to an extent, corresponding to the number of teeth through which thesegment has moved. The tens-transmission is constructed in thefollowingmanner, in order to dispense with the arrangement of a separatetenstransmission for each column-counter:

Each rack 20 is provided with'a springloaded hooked lever 21, whichholds down a x spring-loaded flap-lever, 22 for limiting the can returninto its initial position and thereby rotate the counter-wheel toanextent corresponding to the number set in the machine. Eachcounter-wheel is provided with a tenstooth 23, which during the movementpast arm 24 of the hooked lever 21 turns the latter,

I whereby the lever 22, limiting the stroke of with or disengaged fromthe racks 20 in a certain order, according to the desired operationofthe machine, for example, entering an item in the counter, indicationof an intermediate sum or subtotal in the counter 8, and printing of thetotal. During the usual calculation, e. g. the registration and printingof the amounts with subsequent advance of the carriage, the counters 13have to be engaged only at the same time as the counter. 8. Theengagement and disengagement of the counters is substantially carriedout during the idle stroke of the type-bars 1 from the basic position tothe zero-position. However if it is desired to take a total from thecolumn-counters, it is necessary that the corresponding counter 13 shallbe in the engaged position during the upward stroke of the type bars 1and disengaged during the return movement. indicated in the counter 8 byturning back the wheels of the counter 13 to such an extent by means oflifting the type-bars, until the tens-transmission teeth 23 strikeagainst the arms 24 from the opposite direction and, because the teethdo not find inclined faces at. this side, each counter-wheel is arrestedin the zero-position, whereby the lift of-the type-bars 1 is limited.The latter are now disposed in the position, which corresponds to thevalues standing in the counter 13. The column-counter is now in the zerocondition and ready for a new registration.

Therefore the counters 13 have to be engaged in three different ways,namely either only during the return movement of the typebars or onlyduring their lift and finally for a sub-total during the lift and returnmovement of the same. The arrangement shown in Fig. 2 is suited forcarrying out the said three difi'ere'nt operations. The U-shaped bar 12,already shown in Fig. 1 and pivotally secured to the, slide of thepaper-roller-by means of the levers 11 and carrying the casings 15 ofthe column-counters on the bar 12, is provided with a lateral bar 26which is engaged by rollers 27 and 27 The latter are mounted on one armof a lever 28 furrecesses of a control-disk 30, so that the lever 28 isturned according to the position of the control-disk and thereby the bar12 is displaced and consequently the counters 13 (Fig. 1) arrangedonthesame are moved into or out of engagement with the racks 20 (Fig. 1).The control-disk is rotatably mounted on a pin 31 secured to the frame,and is operated as follows. A lever 32, provided with three arms, ismounted on the pin 31 and one arm of the former is connected by aconnecting rod 33 with the hand operated crank or other driving meansfor operating the machine, so that the said arm moves to and fro throughan arc of ninety degrees when operating the said crank. The second armof the lever 32 carries two pawls 34, 35, the pawl 34 rotating the discclockwise and the pawl 35 anticlockwise. Therefore, dur ing theoperation of the lever-arm, the control disk 30 is turned in one of thetwo direc: tions of rotation. The following arrange- The sum is printedor nished with three arms, each of the two other ment serves forcontrolling the pawls 34 and 35 On the in 31 are mounted two crankedlevers 36, 3 which can be adjusted in different positions to each otherand are provided with pawls 38, 39 extending into the path of movementof the pawls 34, 35.

The pawl 38 operates the pawl 34 during the forward movement and thepawl 39 cooperates with the pawl 35 during the return movement. v

The other arms of the levers 36, 37 are provided with stops 36 37 whichengage .recesses of control segments 40, 41.

The control segments are adjusted b the keys 42, 43 through theintermediary 0 link rods 41, 40 so that the levers 36, 37 come to resteither in position I or II. For limiting the movements of the levers 36,37, spring pawls 44, 45 are provided, the noses of which engage inrecesses 46, 46 on the levers 36, 37 and, during the displacement of thelevers 36, 37 are first of all lifted by the control segments. For thispurpose each of the pawls 44, 45 has lateral pin 50 which engages in aguide of the control segments.

When one of the keys 42 or 43 is actuated, the corresponding controlsegment 40 or 41 is actuated and, by means of its guide which controlsthe pin 50, first of allpulls the nose of'the pawl out of engagementwith the recess 46, whereu on the lever 36 or 37 is released and can erocked by the control segment. In the other extreme position of thelever 36 or 37 the pawl 44 or 45 again snaps into the recess 46 andholds the lever securely in position. As already mentioned, thecolumn-counters 13, which in their inoperative position are out ofengagement with the actuating members 20, are only moved into engagementtherewith, when an item is being entered, during the downward movementof the type bars 1 or the upward movement of the actuating members 20.

Figure 2 shows the position I of the cranked levers 36, 37 of thecontrolling mechanism, in which the column-counters are being actuatedfor the entering of an item.

During this cycle of operations, the pawl 34 is lifted from the lowerrecess of the control disc 30 by the pawl 38, which is situated in theinitial position I, immediatel yat the beginning of the controllingmovement of the three-armed lever 32 actuated by the connecting rod 33.During the further rotation of the lever 32 the pawls 34, 35 are. movedidly along with. it until they drop into the upper recess of the controldisc 30 and then rotate this disc during the remainder of the rotarymovement of the lever 32 clockwise. By this -means the three-armed lever28 carrying the rollers 27, 27 will have been rotated and the movablecolumn-counters 13 swung into engagement with the teeth of the actuatingmembers 20 which are already situated in their lower end position(Figure 6). During the subsequent return movement of the crank, the pawl35 will be lifted immediately from the upper recess of the control disc30 by the pawl 39 of the cranked lever 37 situated in the initialosition I, so that the columncounters 13 in question remain constantlyin engagement with the actuating members 20 durin the upward movementthereof. Atthe end 0 the return movement of the crank, the pawls 34, 35,which during the upward movement of the actuating members 20 have beenslid over the periphery of the control disc 30 by the lever 32, dropinto the lower recess of the control disc under the action of theirsprings and rotate this disc in the anticlockwise direction into itsinitial position in which the counters 13 are again out of engaement)with the actuating members 20 (Figure 2 6 However, before the typebars 1 .have reached their highest position or the actuating members 20their lowest position, the tens flap levers 22 are returned by thereturn rail 25 (Figure 2).

For this purpose the three-armed lever 32 carries on its third free arma connecting rod 49 which, by means of a longitudinal slot provided inthe latter engages a pin on the return rail 25 and pulls the latter downonly during the latter portion of the rotation of the lever 32 in theclockwise direction and thereby causes all the flap levers 22 which havebeen disengaged to come again into engagement (Fig. 6).

During of the rack bars 20 the flap levers 22 are already in theirinitial position ready to perform a fresh tens transfer operation.

If a figure which is not to be added (for instance a number or date) isto be printed, then the counters 13, as above mentioned,must

remain out of all engagement with the rack bars 20 during the upwardmovement as well as the return movement of the type bars 1. For thispurpose, before connecting up the driving mechanism of the machine, thekey 42 .is actuated which moves the cranked lever 37 through the mediumof the control segment 41 into the position II (Figure 4).

During the movement of the three-armed lever 32 in the clockwisedirection, the pawl 34, as above described, is lifted out of the lowerrecess of the control disc 30 and without influencing the latter iscaused to slide over the periphery thereof until it again falls into theupper recess and carries the control disc round with it during theremainder of the rotary movement of the lever 32. The counters 13 movedinto engagement in this manner with the rack bars 20, however, at thebeginning of the return rotation of the lever 32, during which thecontroldisc 30 is returned by means of the pawl 35 engagthe followingupward movement By this means the column counters 13 in question are notin engagement with the rack bars either during the downward movement orthe upward movement of the rack bars.

Therefore the calculation mechanism is dis- 4 engaged and this positionis utilized for typing the numbers.

If the sub-total key 43 is depressed, the control segment and thus alsothe lever '36 will be turned, so that the pawl 38 does not interferewith the start of the movement of the pawl 34 carried by the lever 32,so that during this movement the said pawl remains inthe correspondingnotch or recess of the control-disk and takes along the same, im-'mediately at the beginning of the working stroke, so that thecolumn-counters 13 are moved into the operative position before theracks 20 are operated (Fig. 9). In the outermost position of the lever32, the pawl 35 engages the notch 'of the control-disk 30, but is againdisengaged (lifted off) during the start of the return movement by thepawl 39, so that'the control-disk remains in the position in which .thecounters 13 engage the racks 20. Just before reaching the initialposition, the pawl 35 cooperates with the end'of the other notch of thecontrol-disk and turns the same to such an extent, that these counters13 are disengaged.

This position serves for forming intermediate sums, that is, sub-totals.In view of the fact that the counter-wheels, when forming theintermediate sum, engage the racks 20 during the to and fro movement,all counter-wheels are at first adjusted to zero-position, whereby thesum set in the same is printed by the type-bars 1 and also is entered inthe counter 8, and subsequently the said counter-wheels are returnedagain to the amounts contained therein, so that further set amounts maybe added thereto.

If it is desired to form column-totals, the keys 42 and 43 are depressedand thereb the control-segments 40 and 41 are adjusts and thus thelevers 36 and 37 with the pawls 38 and 39 are turned in oppositedirections to one another. Therefore the pawl 38 permits the rotation ofthe pawl 34 to some extent,

'4 Leeann The simultaneous de ression of the keys 42 and 43 can becarrie out by a separate key 48 (total key), which is. provided with atransverse bar and'cooperates with the levers of both keys 42 and 43.

I claim 1. In a typing'calculating machine withf printing mechanism, atransversely moving paper carriage, anumber of movable counters andactuat1ng members therefor, said countersas well as the actuatingmembers being fitted to the outside of the machine behind and below thefixed counters and typing mechanism, a control-disk moving the -movablecounters into and out of engagement, a pawl-lever operating saidcontroldisk, pawls on said pawl-lever and engaging notches of saidcontrol-disk.
